Kubernetes CKA sample exam question 88 with answer

Question
Create a service called webapp-svc listening on port 8080.
Deploy a pod with label app=web and image nginx as backend of the service.
Deploy an Ingress called webapp-ingress and map it with the service webapp-svc on path /web

Answer
First we need to deploy a pod with label app=web using nginx image. Name of the pod doesn’t matter:

kubectl run nginx --image=nginx -l=app=web

Then we to expose the pod using service name webapp-svc on port 8080:

kubectl expose pod nginx --name=webapp-svc --port=8080

Finally we need to deploy Ingress resource which reaches to service webapp-svc on path /web:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: webapp-ingress
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /
spec:
  rules:
  - http:
      paths:
      - path: /web
        pathType: Prefix
        backend:
          service:
            name: webapp-svc
            port:
              number: 8080

Verify:

kubectl describe ingress webapp-ingress
